KINETIC ENERGY HARVESTING // HIGH-DENSITY FLUID DYNAMICS
At surface level, the CO2 is in a supercritical state, acting like a thick fluid.
Slow surface winds carry massive momentum due to the high density.
Because Power (P) is directly proportional to density (ρ), a turbine on Venus can generate the same amount of electricity as one on Earth, but with wind speeds that are nearly 10 times slower. However, the turbine must be built from ultra-durable materials to withstand the extreme pressure and heat.
